Abstract: A number of digital libraries that aggregate multiple digital collections are now generating subject metadata to describe intellectual content of entire digital collections as integrated wholes and to provide context for individual digital objects within them. However, the utility of this important contextual metadata has not been empirically evaluated. The exploratory study reported in this article examined and compared collection-level subject metadata in three large-scale aggregations of cultural heritage digital collections in the United States and the European Union and analyzed the role of collection-level metadata in information retrieval in digital aggregations based on user search queries derived from transaction logs. A small-scale targeted user study, which combined interviews and observations of users interacting with an aggregation, was undertaken to complement evidence-based content analysis data. The study revealed considerable variability in two indicators: consistency of applying controlled-vocabulary collection-level subject metadata elements beyond topical and value length of metadata elements. Both free-text and controlled-vocabulary subject metadata were found vital in answering search queries of aggregation users. Users also expressed preference for viewing complete structured collection-level metadata records, which include subject metadata. Results of this study prove importance of provision of collection-level metadata in general and subject metadata in particular to enhance user experiences and information retrieval in digital libraries.
